With the coming of Open Science principles, many scientific institutions who were previously aggressively guarding their data decided to put them out for public consumption. Mostly this means other academics look at them and maybe they get your paper retracted for fraud. But sometimes, amateur scientists also use them for decidedly other purposes than what…
Continue ReadingThis one has been a long time in the making. Which is to say, I was too busy doing other stuff to get this done. BUT here we are! Also, just now, more details from EA4 are out. EA4 is the 4th large GWAS for educational attainment, and thus also intelligence. Russell Warne has a…
Continue ReadingSome anon sent me this paper, asked if there was a rebuttal somewhere. It’s a well cited economics paper, 1248 citations on Google Scholar. I wasn’t familiar with it, but reading it over, I see some things comment on. Bowles, S., & Gintis, H. (2002). The inheritance of inequality. Journal of economic Perspectives, 16(3), 3-30….
Continue ReadingNot intended as a proper book review. I didn’t read this book yet. Back in 2019, Bryan Caplan and Zach Weinersmith published a serious comic book Open Borders: The Science and Ethics of Immigration. It does what it says, argues mostly without left-wing shame tactics for the billion dollar bills on the street. Well, I…
Continue ReadingBo Winegard has a thread on this piece here. I didn’t know about it at the time of writing. Boomer woman journalist Cathy Young has a new piece out: The Reality of “Race Realism”. Actually, it’s supposed to be a book review of sorts, but Cathy tells us that she hasn’t read the book, but…
Continue ReadingProbably most social science is done using data that are based on self-report. Thus, they are crucially dependent on assumptions that self-report data reflect objective reality. There are some large studies or meta-analysis that compare self-report to objective results. To take a simple example. Kuncel et al 2005 meta-analyzed self-report GPA versus actual GPA from…

The Negative Religiousness-IQ Nexus is a Jensen Effect on Individual-Level Data: A Refutation of Dutton et al.’s ‘The Myth of the Stupid Believer.’ Journal of Religion and Health. https://doi.org/10.1007/s10943-021-01351-1 A recent study by Dutton et al. (J Relig Health 59:1567–1579. https://doi.org/10.1007/s10943-019-00926-3, 2020) found that the religiousness-IQ nexus…
Continue ReadingThis study keeps getting attention. This otherwise alright Quillette piece: Mate Selection for Modernity Studies using data from classic online dating websites and speed-dating both found that men exhibited less of a preference for women whose intelligence or ambition exceeded their own. A study by four UK universities found that a woman’s likelihood of marriage…
Continue ReadingRussell Warne has a new post: Implications of average group differences for the design of intelligence tests He writes: The implication is that if test creators can force an average difference to disappear for one pair of groups (i.e., males and females), then any differences or lack of differences are also engineered into the tests….
Continue ReadingRaymond Cattell was one of the early 1900s eminent psychologists. Like Meehl, he had a philosophical bent with some odd ideas in ethics. That ended up getting him into trouble (like yours truly). So I found one of his older books, from 1937, so before World War 2, and decided to give it a shot….
